Are the following combinations allowed? If not, show two ways to correct them:
mafiozo [28]

The following combination of n=3 ; l=1 ; ml=-2 is not allowed. One way to correct this would be by changing the azimuthal quantum number, l and the other way would be to change the magnetic quantum number, m.

<h3>Is the following combination n=3; l=1; ml=-2 allowed or not.? If not, suggest two ways through which it can be corrected.</h3>

The following combination of n=3 ; l=1 ; ml=-2 is not allowed.

There are several rules that need to be followed for assigning electron quantum numbers. They are:

1. Principal quantum number should be 1 ≤ n

2. Azimuthal quantum number, 0 ≤ l ≤ n − 1

3. Magnetic quantum number, -l ≤ ml ≤ l

4. Spin quantum number as either -1/2 or +1/2

For n = 3,

l should be n - 1 or n - 2 or n - 3 = 2, 1, 0 respectively.

If we choose l = 1 then ml should be -1, 0 and +1

Therefore, one way to correct the combination would be to change the magnetic quantum number to -1

If we choose l = 2 then ml would be -2, -1, 0, +1, +2

Thus, another way to correct the combination is to choose the azimuthal quantum number as 2.

Thus, the following combination of n=3; l=1; ml=-2 is not allowed. One way to correct this would be by changing the azimuthal quantum number, l and the other way would be to change the magnetic quantum number, m.

What could a scientist do to determine what era the Eocene period belongs to on the geologic timescale?
Aleks [24]

Answer:

Study information related to the Cenozoic era

Explanation:

Answer:

Study information related to the Cenozoic era

Explanation:

Eocene can be categorized as early epochs, It comes after the Paleocene Epoch and precedes the Oligocene Epoch. Eocene got it's origin from the Greek eos meaning ( Dawn). The beginning of Eocene produce the two appearance of two new groups of animals among the terrestrial vertebrates which are; the artiodactyls and the perissodactyls.

Eocene Epoch is reffered to as the second epoch in the order of the division of Cenozoic period . therefore, there is need for scientist to study information related to the Cenozoic era in other to know the geological time scale Eocene belongs to.
